Abstract
Abstract
Background: The aim of our study was to compare the change difference in contrast sensitivity after laser in situ keratomileusis (LASIK) and photorefractive keratectomy (PRK) in cases of mild and moderate myopia.
Methods: Our study included 50 patients with a total number of one hundred eyes subdivided into 2 groups: the first group included 25 patients who underwent uneventful bilateral LASIK surgeries, and the second group included 25 patients who underwent uneventful bilateral PRK surgeries, age was ranging from 18 to 40 years old, with measurement of contrast sensitivity before and after surgeries 1 week, 1month and three months using the Pelli-robson contrast sensitivity chart.
Results: It was found that Contrast sensitivity changes were significantly higher in patients managed with PRK surgery than in patients managed with LASIK surgery.
Conclusion: Contrast sensitivity measurement is a good method as visual quality indicator after refractive surgeries such as LASIK and PRK.
